The 31-year-old clarified his comments on Twitter by saying: "Rooney is our best player at the moment. Put in context for me, by my definition of 'World Class', he isn't. I'm sorry thats my belief.
"He is infinitely better than me. That is not the debate here. But I was never World Class, so people are missing the point. Now shall I tell you what World Class is for me. Ronaldo and Messi. Iniesta and Suarez. WC is a term thrown about far too often. Maybe Wayne was has been in WC bracket before. I would have to say now he isn't.
"Why? Well it isn't for the lack of talent IMO. I would have to argue that he has not been better since he broke on the scene at Everton. For me thats when he stopped developing or just afterwards. As I say, he is a top player. My favourite of the current bunch. Love watching him. Old school. But not World Class IMO."
England will begin their World Cup campaign in Brazil this summer with a group clash against Italy on June 14.
